Kentucky sues Kalshi, Polymarket and VGW over alleged illegal gambling offerings

The state also named Coinbase in the Kalshi case as it presses a wider legal fight over whether sports-event contracts fall under state gambling law or federal derivatives oversight.

Fact Check
Multiple independent Kentucky local news outlets (LEX18, Courier-Journal, WHAS11) and Cointelegraph confirm AG Russell Coleman filed three lawsuits on June 17, 2026 against Kalshi, Polymarket and VGW alleging illegal/unlicensed gambling. Coinbase was named in the Kalshi case as a partner accused of facilitating unlicensed sports gambling. The sources confirm the core legal dispute over whether sports-event contracts are state gambling/sports wagering or federally regulated derivatives (CFTC jurisdiction), exactly matching the claim.
Summary

Kentucky Attorney General Russell Coleman sued Kalshi, Polymarket and VGW on June 17, accusing them of operating illegal gambling platforms without a Kentucky licence. The lawsuits allege Kalshi and Polymarket offered sports-related event contracts that functioned like wagers on game outcomes, odds and player statistics, while VGW allegedly ran sweepstakes casino sites using virtual coins that could be exchanged for cash prizes. Kentucky also named Coinbase in the Kalshi-related case, alleging it acted as an affiliate or partner in unauthorized sports contracts. The actions deepen a broader clash over whether prediction markets should be treated as gambling subject to state law or as federally supervised derivatives markets under the CFTC. The dispute comes as Kentucky faces a separate industry lawsuit over a new 14.25% excise tax on prediction-market transaction fees and ahead of a July 15 state law that will bar licensed sportsbooks from contracting with operators such as Kalshi or Polymarket.
